Detailed Explanation of Green Bean Planting Time and Methods

Green beans are one of the common vegetables on our dining tables. Their mild and pleasant taste makes them well loved, and they are cultivated in both northern and southern China. So do you know their planting time and planting methods? Below, Qinnong Network brings you the planting time and planting methods of green beans. Let us learn about them together.

Planting Time

Green beans can be sown in spring and autumn. They like a warm environment and are not cold-tolerant. The seeds only germinate between 20-30 degrees, so the sowing time differs by region. In spring, temperatures in southern regions rise quickly, so spring sowing in the south is in January-March, while temperatures in northern regions rise slowly, so sowing is in April-May. In autumn, temperatures in northern regions drop quickly, and the sowing time is generally August-September. Relatively speaking, southern temperatures are higher, and August-September is still midsummer, when temperatures are relatively high and not suitable for green bean germination, so sowing is generally chosen for September-October.

Planting Methods

1. Temperature: Green beans like a warm environment and are not tolerant of frost, so the optimal growth temperature is 20-30 degrees. Temperatures above 40 degrees or below 10 degrees are both unsuitable for their growth. The seedling stage is especially extremely sensitive to this, and in severe cases it can cause the plants to die.

2. Light: Green beans are short-day plants, and their daily light requirement is limited. They cannot remain in a sunlight-exposed environment for a long time. There are many varieties, and different varieties have different light requirements.

3. Water: Green beans are one of the few vegetables with a well-developed root system. Their main root is thick and strong, with many lateral roots. They are relatively drought-tolerant and afraid of waterlogging, so when planting, watering should not be excessive. Conversely, during the rainy season, drainage should be done promptly.

4. Soil: Green beans are suitable for planting in loose, fertile, well-drained humus soil. Ordinary sandy soil and slightly clayey soil can also allow normal growth, but they should not be grown in low-lying, easily waterlogged soil. The soil is best neutral, and should not be too acidic or too alkaline.

5. Fertilization: Green beans have a relatively large demand for nitrogen and potassium fertilizer, and a relatively small demand for phosphorus. When fertilizing, try to apply farmyard manure based mainly on nitrogen and potassium fertilizer.

6. Weeding and Trellising: When the green bean vines begin to grow, 1-2 rounds of loosening the soil and weeding should be combined with this. When the plants are seen to be vining, trellises should be set up promptly to guide the vines, which makes management easier.

7. Pest and Disease Control: When planting, choose varieties with good disease resistance, choose land where legume crops have not been planted for more than two years, and clean and disinfect the soil and seeds before planting. Deal with pests and diseases promptly when they are found.

The above is the green bean planting time and planting methods brought to you by Qinnong Network. We hope it can help you. The editor also reminds everyone that when we stir-fry green beans, we must cook them thoroughly, otherwise it may cause a poisoning reaction.
